London Leads England's Measles Outbreak

As the summer vacation season peaks in late July, international travelers should be aware of where the measles virus is spreading.

According to data from the UK Health Security Agency (UKHSA), 529 laboratory-confirmed cases of measles were reported in England in 2025.

The unfortunate leader is London, with 44% (233 of 529) of these cases.

Other measles outbreaks have been reported in the East of England, the North West, Bristol, Hackney, and Leeds.

To alert all travelers, the U.S. CDC updated its Level 1 - Practice Usual Precautions, Global Measles alert at the end of May 2025.

The UK's NHS says Measles is an infection that spreads very easily in areas such as airplanes, trains, and closed spaces like conference centers.

However, obtaining the MMR vaccine is the best way to prevent infection.

In the United States, MMR vaccines are available at clinics and pharmacies. The CDC recommends vaccination weeks ahead to visiting measles-risk areas in 2025.
